Composition and Properties:
Stainless Steel 321 is an austenitic stainless steel alloyed with titanium, which provides several advantages over standard 304 and 316 stainless steels. Its key properties include:
- Corrosion Resistance: Stainless Steel 321 offers superior resistance to general corrosion and intergranular corrosion in elevated temperature environments, making it suitable for applications where exposure to corrosive chemicals or high humidity is a concern.
- High-Temperature Resistance: This alloy retains its strength and corrosion resistance even at temperatures up to 1500°F (816°C), making it ideal for use in heat exchangers, furnace parts, and other high-temperature applications.
- Weldability: Stainless Steel 321 is readily weldable using most standard welding methods, making it a preferred choice for fabrications that require joining or forming.
- Mechanical Properties: It exhibits excellent tensile and creep strength, ensuring long-term performance in demanding conditions.
